SPECIFICATION forming part of Letters Patent No. 273,426, dated March 6, 1883.

- f Application tiled April 28, 1882. (Model) To all whom it may concern:

Be it known that I, FRANCIS M. ALLEN, of Knoxville, in the county of Knox and State ot' Tennessee, have invented a new and Improved Gultivator, of which the following is a full, clear, and exact description.

This invention consists of improvements in cultivators, whereby it is designed to con' struct them so that they will run upright on side-hills as well as on levels, and at the same time the several plows or teeth will work to an equal depth in the ground, whereby, when cultivating growing corn, the corn will be less injured by the machine than by those machines that incline with or work in a plane parallel with the surface of the ground.

The invention also consists of certain details of construction, hereinafter more fully set forth, and pointed ont in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specitcation, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is partly a plan view and partly a horizontal section of the machine. Fig. 2 is a transverse section of Fig. l on lineyy. Fig. 3 is partly a side elevation and partly a sectional elevation of Figs. l and 2.

A and B represent plow stocks or beams, which are alike, except that the one marked B is a little longer than the other, A, the said stocks consisting ot' plain bars crooked at the rear ends suitably for serving for coltivatorteeth or as shanks for the attachment ot' plows ot' any approved form. These plows are to be used in gangs of two or more, and the outer ones have handles D, to be connected to the front end of the beams by clips G.

The rear connection of the handles to the beams is made by curved standards H, on which the handles can be shifted up and down on the centers G, according as it may be desirable to vary the'height of the handles. To these standards H the handles are connected above the beams and at the required height therefrom' by the clips I and keys J. t

The two outside plows are to be connected across the space 1from one to the other by means allowing them to rise and fall independentlyr of each other, also to vibrate laterally, so as to be held upright on side-hills, and also allowing one or more intermediate plows to be applied between them, and to allow said intermediate plows to rise and fall and vibrate in the same manner as the other ones do. T his is accomplished by the frame, consisting ot angle-bars T, with blocks V between them at the ends, and pivoted at fr, and the top plate, W, yoked to the upper ends of said blocks and secured by pins Y, the joints being slack, so that said frame will have lateral vibration to allow the plows to be held upright by the plowtnan. Upright bars P' will also be used with the frame, and they will be connected by a cross-bar, Z, at the top, and the top plate, W, will have the holes through it for the blocks V, extended so as to embrace the barsV P and H. This frame will carry yokes Q, also for the intermediate plows, but they will be suspended from the angle-bars T by rollershaped bars a, reduced in size between the ends about the thickness of the yokes, so that the rollers, lying close together and touching one another from side to side between bars P', will keep the yokes employed in position, whether one or more is used, and being so that the yokes can be put in on one or the other of said rollers, as may be required.

The bars P extend through the frame T W, allowing the same to vibrate, and these parts,

projecting below, are designed to serve as pulverizing-teeth to act upon sods,1umps, and other matters oflike character upon the surface, and, together with them, I propose to apply other points, d, by hanging them from rollers a, between the links Q, in which the plows are located. IVith these pulverizingpoints I propose to employ fine teeth upon the plow-stocks, and thus practically convert the cultivators into a harrow.

The plows are interchangeable, sosthat they may be arranged in the order represented in the drawings, or in any other, and two, three, or more may be employed in a gang, as desired,.using two hooks to connect each pair separately. Whenfourplows areused,orwhen three are used, they may be coupled to a bar, e, having two hooks, as in Figs. l and 3, and in this case the three beams are coupled to- IOO gether at the front by oblique struts g, pivoted to the respective plows, so that they may rise and fall independently ot' each other. The clips connecting said bars H to the handles consist of side plates, I, and cross-plates t, connecting said side plates above and below the handles. Clips Gr consist of bands bent around and Welded at the ends. Said bands are bent obliqnely at the top and bottom of the beam to malte the required taper form, and they are secured in position by set-screws j.

Having thus described lny invention, I claim as new and desire to secure by Letters Patent- 1. The con1bination,in a cnltivator,ofplows A, handles D, standards H, and a frame connecting said plows in a gang, said frame having two or more yokes, Q, for intermediate plows, connected at the top by a bar, z, substantially as described.

2. The combinatio11,in a cultivator,ot` plows A, handles D, standards H, and bars P, said bars P projecting below the connecting-frame and forming pulverizing-points d, substantially as described.

3. The combiuation,in a cultivator,otl plows A B and pulverizing-points d, suspended from the beams of the plows in advance ot the plows, substantially as described.

4. The combination, in a cultivator, of plows A, handles D, standards H, and a connectingframe consisting of angle-bars T, bar W, and connecting blocks V, substantially as described.

5. The combination,in a cnltivator,ofplows A, handles D, standards H, bars P', and roller-bars a, substantially as described.

6. Theeombination,iu a cultivator, with two or more gang-plows having parallel beams coupled to the bar e by hooks, of the oblique struts g, pivoted to the respective plow-beams, so as to rise and fall independently ot' each other, substantially as described.

7. The combiuation,iu a cultivator,ofplows A, handles D, standards H, connecting-frame T W, roller-bars te, and yokes Q. for intermediate plows, suspended from said roller, substantially as described.

8. The combination,in a cultivator, of plows A, handles D, standards H, connectingframe T W, roller-bars a, and pnIverizing-poiuts d, suspended from said roller-bars, substantially as described.

9. The combinatioinin a cultivator, of plows A, handles D, standards H, bars P', connecting-frame T 7, gibs M, and clips N, substantially as described.
